Mosmi Tiwari, Amrita Tiwari, Deepak Sukheja . Modified Hop Count Analysis Algorithm (MHCAA) for Preventing Wormhole Attack in WSN. Communications on Applied Electronics. 3, 3 ( October 2015), 6-10. DOI=10.5120/cae2015651896
Wormhole attack is one of severe security threat may apply on network layer. It is a passive attacks aims to drop packets by creating illusion of shortest path from source to destination. Wormhole nodes attempt to attract the genuine nods by showing an illusion of shortcut from source to destination and registered themselves as next hop at source routing table. When source consider wormhole tunnel as shortest route and transfer packet to wormhole node they start dropping packet respectively. This paper considers this problem as severe issue an attempt to derive a mechanism to detect and prevent wormhole node in mobile ad-hoc networks. The objective of this paper is to study various ways to create wormhole attack and develop techniques to detect and prevent wormhole node using AODV routing protocol.
